Use this skill to run a complete, repeatable reverse-engineering workflow for endpoint security products. Apply the same structure to every product so outputs can be compared across analyses and future work can resume without rediscovery.

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

Abstract: This document teaches you from the very basics to advanced features such as std::launder how pointers in C++ work. It is aimed at developers of any skill level. However, it links to the C++ standard so that advanced readers can verify the information and investigate further.

Motivation: Most tutorials on pointers are aimed at beginners, and present a simplified model. Some tutorials perpetuate an explanation of pointers that is solely based on their implementation (pointer = memory address). This tutorial aims to provide a comprehensive explanation of pointers that is in line with how they actually work from a language perspective.

Bluesky has implemented age verification measures in response to regional laws that restrict access, prompting users to verify their age through Epic Games' Kids Web Services before they can access adult content.

This sucks, but thankfully there are ways to work around it.
